besides it is acceptable anyway.
Never start a sentence with a conjunction. Admittedly, starting a sentence with a conjunction can leave the reader confused with what preceded the “and,” “or,” “but,” or “yet.” It automatically creates a sentence fragment, because, if you lift the sentence off the page, it makes no sense at all. But sometimes starting with a conjunction can add vividness, power, and flow to thought. That’s why there are so many conjunction-opening sentences in advertisements, direct mail, newspapers, speeches, and e-mails. They mirror the way we actually speak. *nods*
